Observables,bert space. There exists an alternative approach which refers directly to the operationally relevant features of these observables. This . has the advantage of being open to the consideration of unsharp observables, which turns out necessary in some cases where sharp ‘observables’ simply do not exist or are not amenable to measurements.

Phase Space,rges as an approximation to the former in circumstances under which Planck’s constant can be regarded as small. On the side of the states one would have to explain why superpositions of (vector) states representing macroscopically distinct properties of large systems are practically never observed. We do not enter into this difficult issue here.
